Message-ID: <20220916184132.1161506-1-namhyung@kernel.org> (raw)

Hello,

This fixes random failures in the perf stat cgroup BPF counters (bperf).
I've also added a new test to ensure it working properly.

v2 changes)
 * fix a segfault with uncore event

You can get it from 'perf/bperf-cgrp-fix-v2' branch in

Thanks,
